Can you exchange some dollars into euros?
cam-BIA-re — three syllables, stress on the second.
Ask at reception if you need currency exchange. Most Italian hotels can exchange major currencies, though at less favourable rates than banks.
'Potete cambiarmi' = can you exchange for me. 'Dei dollari in euro' = some dollars into euros. 'Dei' is the partitive article. Italian hotels that offer currency exchange ('cambio valuta') typically use rates that include a commission — always ask the rate before agreeing.
Qual è il tasso di cambio oggi?
What is the exchange rate today?
Always ask the rate before exchanging — hotel rates include commission
Dove trovo un ufficio di cambio?
Where can I find an exchange office?
Ask for the nearest 'ufficio di cambio' if the hotel rate is unfavourable
Accettate dollari americani?
Do you accept US dollars?
Some Italian tourist areas accept USD directly, though the rate is rarely favourable
Currency exchange at Italian hotels is convenient but expensive. The best rates in Italy are at post offices ('Poste Italiane') or banks, and the worst are at airport exchange booths. If you have a credit card with no foreign transaction fees, using it directly is almost always better than exchanging cash.
